Self-tapping hex screws are specialized fasteners designed to tap their own threads as they are driven into materials like metal, plastic, or wood. The "Hex" head profile provides superior torque transfer, reducing slippage and ensuring a secure fit in high-vibration environments such as automotive assemblies and renewable energy infrastructure.
Unlike standard screws, OEM Self-Tapping Hex Screws utilize specific lead-in thread geometries to minimize radial stress. This is critical for preventing material fatigue in thin-walled components used in New Energy Vehicle (NEV) battery housings and circuit breaker enclosures.
Procurement heads in North America and Europe are shifting toward "Consolidated Supply Chain" models. They seek manufacturers who provide not just a component, but a total fastening solution including anti-corrosion coatings (like Dacromet or Zinc-Nickel) and automated quality verification.
At Zhejiang Jifeilong Instrument Technology, we have transitioned from traditional workshops to fully automated production lines. Our Industry 4.0 integration allows for real-time monitoring of tolerances, ensuring that every batch of Hex Head Self-Tapping Screws meets the stringent requirements of ISO9001 and international electrical standards.
Located in the Oujiang Port industrial cluster of Wenzhou, our factory leverages a localized ecosystem of raw material suppliers and logistics hubs. This geographical advantage minimizes lead times and shields our global partners from the volatility of international freight disruptions.
With over two decades of experience since 1999, our expertise spans carbon steel, stainless steel (SS304/SS316), and specialized alloys. This deep material knowledge allows us to consult on the best fastener choice for harsh environments, such as solenoid valves and filtration equipment.

Our hex screws and rivets are fundamental in the assembly of Molded Case Circuit Breakers (MCCBs) and Miniature Circuit Breakers (MCBs). Precision is vital here to ensure electrical conductivity and structural integrity under high heat.
In EV charging piles and battery packs, fasteners must resist corrosion and vibration. Our custom copper cylindrical head parts and high-performance pins provide the reliability required for the future of mobility.
High-precision nozzle components and valve core accessories are used in fluid control and solenoid valves, where mechanical tolerances are measured in microns.
Established in September 1999 (formerly Yueqing Feilong Instrument Factory), we are a powerhouse in the manufacturing of electrical switches, shafts, hardware components, and fastening solutions. Located in Wenzhou City, we have evolved through technological innovation to become a global supplier of high-precision components.
Our Mission: To be realistic and prioritize quality above all else. We strive to provide the precision foundations for global industry through continuous system and management innovation.
A: For standard OEM specifications, we typically process and ship within 3 to 5 days thanks to our fully automated production lines. Custom tooling orders may vary but are expedited through our in-house grinding and processing departments.
A: We strictly implement ISO9001 standards. Every production link, from raw material procurement to finished product delivery, undergoes rigorous QC protocols. This ensures that fasteners used in circuit breakers and switches meet international safety standards.
A: Yes, our expert engineering team provides free samples and tailored design services (OEM/ODM) to ensure the fasteners meet your exact mechanical and chemical specifications before mass production.
A: We recommend high-tensile carbon steel with specialized heat treatment or 300-series stainless steel for maximum corrosion resistance and durability in automotive or filtration equipment.
